In one of my question, I decided to post an answer as a community wiki The reason as stated in the answer:
I decided to make a community wiki because all the answers have good points but none covered all the aspects.
It serve as a summary of the different answers posted. I might also add more content to complement it. I was expecting to do the same this with Creating a realistic world - Spreading religions. I'll try to use the wikis only when it's necessary: when I can't pick an answer as the accepted one because all the answers are good in their own way.
Is it the best course of action?
